BBCE FOR TRACTOR FLOWS.

i I .application ledmarch All, 1922. Serial No. 5461,354.

l0 attachment for tractors which is mounted directly upon the side ofthe tractor so as to work in advance of one of the rear tracto-1 wheels.The front axle of the tractor is connected with a stub axle by anextension cou"- pling or box and the front tractor wheel is carried bythe said stub axle, a diagonally disposed beam being disposed betweenthe extension coupling or box anda supporting bar held at its front endby a plate on the 2,0 rear eng( of the tractor vcrank case and securedav its rear end to the tractor draw bar. This diagonal beam carries theplowsfand their mountings and in actual use has been found 'tosuiciently revent rearward bendi of the axle or of the stub axle. There'is, however, a tendency of the front axle, the stub axle, and the exten-"sion coupling to twistl rearwardly at their under sides, and it is theprimary object of my present invention to overcome this tendency softhatthe axle will be held ri4 id and the tractor wheel be vheld'torits truepath.

This object l attain in the use of such a de- .'vice'as is illustratedin the accompanying drawingspand the invention resides 1n cerv tainnovel features which will be particularly pointed out in the appendedclaims. In the drawings- Figure 1 is a front end elevation of the avingmy improvement applied thereto;

Fig. `3 is a view. partly in section and partly in elevation showing theimprovement;.' d

Fig. 4 is a detail view showing themanner in which the device isconnected with the `50 rear end of the crank'case;.

Fig. 5-is a plan view of another form of the invention. i

The tractor 1 is illustrated conventlonally and is of a well-knowntype.w In mounting socket 18 andi;y u in the said socket, l engage therear end of the above referred to plow upon the tractor, l'

the front axle 2 is equipped with a coupling oi" extension box 3 and thetractor wheel 4:' is carried by a stub axle -which is secured in theOuter end of said extension o-r coupling box by a set screw 6 mounted inthe front 60 side of the couplinfr and clamping the stub axle to themain ax e, as will be readily understood upon reference to Fig. 3, thecou- .plilng being secured upon the main axle b passed verticallythrough the axle and the coupling. The coupling or extension box 3, isprovided upon'itsy upper side'- with apost or lug 8 tov which is securedabearin block 9 which may be pivotally adjuste rlhe block 9 receives thereduced -circular 7o front end 10 of a beam 11 which extends diagonallyrearward from t' e block and has its circular rear end 12 itted injasocket or bearing 13 forming a. part of a T-tting 1li which is mountedon the supporting bar 15.

Said supporting bar 15 is carried adjacent its front end by a bracket orplate 16 secured rigidl to the ange of the tractor crank case, t e barl15 extending Arearwardly and being secured at its tractor draw bar. rlheplows 17 are carried by brackets 18 which are secured to the beam 11,and it will be readily noted that the said beam may rock in its bearingsso that the plows may be easily raised or lowered by manipulation of ahand lever (not shown). i

In carrying out my invention, in the form illustrated in Fig. 5, lprovide an additional socket 19 on tA e T-ittin e side oi the tractor,`and a brace rod 2O which has its front end mg 'jected under lthe axleextension or coup i box 3 and secured thereto by the bolt 7 tendone ofthe axle lto rotate about its own longitu inal axis sothatit-will twistrearwardly at` its under' side is overcome by the .provision of thisbrace bar so that the axle will remain rigidly at its work, relativeplay between thebar 15 and the axle will be permitted, this result beingdue to the sti'nes's ofY the brace rod and the end thrust resistance ofthe rod after all the play of the rod in the socket 19 has been takenup. 105

In the form of the invention shown 1n Fig. 3, the brace bar comfprises ametallic bar or nrap 21 havingits ront) end secured l rear end to the 8014 between. the 90 The although frigidly to the underside of thecoupling box 3 by the bolt 7 and its rear end provided with aongitudinal notch or slot 22 adapted to engage over the fitting 1 4 orthe bar 15. A slight play longitudinally of the brace upon the fittingis thus permitted While' at the same time the thrust upon the axle isefectually counteracted. In actual practice, I have made the notch 22 ofsuch length that its base is never touched by the fitting 14 or the bar15 and have employed a brace bar of suclndimensions that its stiffnessaccomplishes the desired results. This Jform of the invention isadvantageous in working on very uneven 'ground as, under suchcircumstances, it is very desirable to have ample play in the notch orslot.

In both forms of the invention, the oonstruction is exceedingly simpleand the device may be applied to the implements now in use as well astosubsequently manufac' tured implements at a very low cost While itwill lincrease the-value and eliciency of the implement by preventingthe twisting of the front axle.

Having thus described the invention, what is claimed as new 1s:

l. In an agricultural implement of the" bar, of a brace having itsyfront end securedy rigidly to the under side of the tractor axle andits rear end provided with `a longitudinal notch engaging said frame baradjacent the rear end of said beam; i*

2. The combination with an agricultural machine comprising a. tractorhaving a front axle, a stub axle, an extension coupling connecting thefront axle and the stub axle, a frame bar supported by the rear portionof the tractor, and an implement-carrying beam supported by the couplingand the frame bar, of a rigid brace barixed at its front end to theunder side of the' coupling and loosely supported at its rear endiuponthe frame bar.

In testimony whereof I aix my signature.
